中心市街地・商店街の衰退と新たな「まちの機能」の担い手について―商店街による七夕祭りの衰退と工夫の比較研究―
丸谷浩明(京都大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:中心市街地やそこに存在する商店街は、従来、まちの顔、賑わい、出会いの場、治安など、さまざまな機能を似ない、これは外部経済効果を有するものであった。近年の中心市街地の衰退により、この貴重な機能を担うことが難しくなっており、それを、市民、ボランティア、他地域企業などの新たな担い手が代わりに担う努力をしなければ、地域全体の損失となる。具体例として旧清水市の七夕を取り上げ、各地の七夕との比較しながら議論する。

製造業中小企業の分析から見る京都の産業クラスターとしての発展の課題―平成17年度産業クラスター研究報告書より―
児玉俊洋(京都大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:京都には、ハイテク有名大企業と産学連携に積極的な大学の集積があるが、中小企業には産業クラスター(産業集積の中に産学連携や新製品開発目的の企業間連携が発達したものとして定義)形成の担い手となりうる企業はどのくらい存在するであろうか?本報告では、「平成15年度京都市ものづくり産業調査」の個票データを用い、首都圏西部のTAMA地域に見られる製品開発型中小企業との比較も踏まえ、京都市の機械金属系製造業の中小企業の研究開発や産学連携に関する分析結果を紹介し、京都が産業クラスターとして発展するための課題を検討する。なお、本報告は、平成17年度に独立行政法人経済産業研究所から京都大学への委託事業として作成した「産業クラスターに関する研究事業に係る調査研究報告書」を活用して行う。

Three-region model of industrial specialization and trade
井村美根(京都大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:The purpose of this paper is to examine how the transportation costs of final good and intermediate goods influence on the location of firms. We develop a three-region model in which the production of final good requires differentiated intermediate goods. Although a region provides lower labor cost, when the transportation cost of intermediate goods is high, no firms relocates to that region. However, as the transportation costs of intermediate goods becomes lower, firms in the final good sector relocate to that region and launch assembly production with intermediate goods imported from the other region.

An economic analysis of municipal consolidation with heterogeneous preference
寺地祐介(京都大学・院)
京都大学経済研究所本館1階 第二共同研究室
要旨:This paper studies the conditions for the consolidation of political jurisdictions. We focus on the tradeoff between the scale merit and the heterogeneity of preference among residents. That is, large jurisdictions enjoy the benefit of scale but must incur the cost due to the increment of heterogeneity among their populations. In addition to this, the land public ownership yields the strategic interaction: the agreement of the consolidation of some towns induce the consolidation of remaining towns. Our model implies that i) the consolidation might be too much observed under the decentralized regime; ii) observed number of the consolidation might be inefficiently large.

Economic geography and the strategic provision of public infrastructure
近藤広紀(信州大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:We construct a framework in which public infrastructures that reduce transportation costs are explicitly introduced in new economic geography models in which the sectors with vertical linkages are concentrated in a limited number of countries. Using this framework, we consider the outcome of the public-infrastructure-provision games by welfare-maximizing governments. In the model, a pure strategy Nash equilibrium does not necessarily exist. We show that there exists a mixed strategy Nash equilibrium in which the public infrastructure investments by a country lacking a sector with vertical linkage have much larger variance than those by a country hosting the sector. The less industrialized country has the incentive to outlay tremendous amounts of public infrastructure investment to attract the sector within its own borders. Consequently, the relocation of an industry with vertical linkage can occur with a small but definitely positive probability.

Home bias for intermediate and finished goods: Evidence from East Asia
早川和伸(慶応義塾大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:In East Asia, international production/distribution networks have developed and have explosively increased intra-regional trade particularly in intermediate goods. This paper examines whether home bias for intermediate goods gets smaller than that for finished goods in the 1990s. Our findings are summarized as follows. First, differences in location advantages, for which we use differences in per capita GDP as a proxy, are more effectively utilized in intermediate goods transactions. Second, the home bias for intermediate goods has been at the same level as that for finished goods. Particularly in 1995, the home bias in all countries is not smaller for intermediate goods than for finished goods.

Geographic concentration of manufacturing industries in Japan: Testing hypotheses of new economic geography
秋田隆裕(国際大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:This paper investigates the changing geographical pattern of manufacturing industries in Japan between 1985 and 1995 and explores factors of their geographic concentration. A regression analysis is conducted to test some hypotheses that are derived directly from early models of the New Economic Geography (NEG). Regression results indicate that the geographic concentration of Japanese manufacturing industries seems to be determined by some combination of internal economies of scale, transportation costs, and factor intensity. However, inter-industry linkages are found to be an insignificant factor of geographic concentration. As posited by the NEG theories, Japanese manufacturing industries with larger internal economies of scale and smaller unit transportation costs tend to have a higher level of geographic concentration. Japanese manufacturing data also support the Heckscher-Ohlin theory: labor- or capital-intensive industries tend to have a higher level of geographic concentration.

中国における持家住宅政策と都市空間構造に関する分析(姜雪梅と共著)
佐々木公明(東北大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:本稿は高所得者が商品住宅を消費し、低所得者が「経済適用性住宅」を消費する中国の持家制度に基づいて理論モデルを構築する。比較静学分析と政策評価シミュレーション分析によって、中国の持家政策が社会厚生、都市空間構造などに与える影響を評価する。分析の結果、1)高所得者の所得増加は都市境界を拡大させ、2)都市内側境界の地代が上昇すると都市内側地代は上昇し都市境界は縮小し、3)適量の「経済適用性住宅」を供給すると高、低所得者の住宅消費は改善され社会厚生は上昇する。

New economic geography with heterogeneous preferences: An explanation of segregation
曽道智(香川大学)
京都大学経済研究所本館1階 第二共同研究室
要旨:Tiebout hypothesis (residential choice depends solely on local public goods) is extensively applied to explain geographic segregation. However, Rhode and Strumpf (2003) find that the Tiebout hypothesis is inconsistent with the long-period empirical data, and therefore a non-Tiebout explanation is needed. This paper provides such an explanation based on the new economic geography framework, into which the heterogeneous preferences of mobile workers on private goods instead of public goods are incorporated. Specifically, two types of mobile workers have different preferences on the products of two industries in the manufacturing sector in a symmetric way. The rigorous general equilibrium analysis conducted here shows that the increasing-returns technology and monopolistic competition form a mechanism endogenously leading to persistent residential segregation. There is an evolving path with decreasing transport costs, in which the two types of mobile workers are segregated, while two industries evolve from dispersion to agglomeration.
